This is a continuation in part of application Ser. No. 09/736,050, entitled “Customizing a Digital Camera for a Plurality of Users”, filed 13 Dec. 2000 now U.S. Pat. No. 6,903,762.
FIELD OF THE INVENTIONThis invention relates generally to the field of cameras, and in particular, to customizing the design and behavior of such cameras for particular demographic groups.
BACKGROUND OF THE INVENTIONThere are aspects of image quality and camera complexity and cost that can be optimized for use by specific demographic groups. An example of a feature set for which the optimum configuration depends on demographic factors are those features pertaining to the reduction or elimination of the image artifact called redeye. As is well known in the art, redeye may occur when the angle between a narrow light source, the photographic subject, and the camera lens is less than approximately three degrees. This criterion is frequently met in flash exposures from compact cameras. The light from the flash enters the pupil nearly on-axis and propagates to the fundus of the eye, where it is reflected back out of the eye, having been colored red by the blood vessels in the fundus. The light exits the eye in a narrow cone, and if the camera lens falls within that cone, the red reflection will be recorded, and may appear in the final image as a red glow in the pupils, which is very undesirable in terms of image quality.
Redeye is more objectionable when the size of the pupil in the viewed image is larger and when the red saturation of the pupil is greater. The former may occur when the pupil is dilated, as occurs at low ambient light levels, or when the subject is rendered at a larger size in the image, for example due to shorter camera to subject distance, longer camera lens focal length, higher printing magnification (including zoom and crop), and/or shorter viewing distance. The primary techniques used in the camera to reduce or eliminate redeye are: increasing flash to lens separation; firing a preflash to transiently stop down the pupil in response to the bright light; and decreasing lens focal length and/or electronic zoom.
While all these methods are efficacious, all have associated disadvantages. Increased flash-lens separation may lead to more expensive and bulkier cameras and produces more noticeable shadows due to the farther off-axis lighting. After a preflash is fired, the eye requires half a second or more to respond fully, and during this delay between the preflash fire and the image capture, facial expressions of the subject often change in an undesirable fashion due to the annoyance and surprise of the preflash. The preflash also increases camera cost, reduces the power available during the main flash pulse, and increases battery consumption. Finally, restriction of optical or electronic zoom factors interferes with the photographer's ability to obtain the desired composition, with the subjects appearing large enough in the image to provide a pleasing rendition.
Digital cameras, such as the Kodak DC26O™ digital camera, sold by the Eastman Kodak Company, enable images to be utilized on a home personal computer (PC), printed locally or remotely, and incorporated into e-mail documents and personal World-Wide-Web home pages which can be accessed via the Internet. The camera's graphic user interface (GUI) enables many different features to be selected, but it is complicated, and thus, very difficult for a first-time user to understand. The camera provides a fixed set of features to the end user. These features can be controlled by Digita Scripts specified by Flashpoint, Inc. Digita Scripts are ASCII text files created with a text editor on a host computer. Such Scripts may be invoked to select particular camera features and to perform a defined sequence of camera operations. For example, a Script may capture an exposure series of still pictures using different exposure settings.
This type of camera design presents several problems, including the fact that any feature that is likely to be demanded by even a small subset of the users must be included in the camera. A consequence of this is that the complexity of digital cameras has increased. This leads to an increase in user anxiety, and therefore, serves as a barrier to market adoption.
The firmware in the DC26O™ digital camera, for example, can be replaced via a memory card, as described in commonly-assigned U.S. Pat. No. 5,477,264, entitled “Electronic Imaging System Using A Removable Software-Enhanced Storage Device,” the disclosure of which is herein incorporated by reference. Images can be assigned to albums, as described in commonly-assigned U.S. Pat. No. 5,633,678, entitled “Electronic Still Camera For Capturing And Categorizing Images,” the disclosure of which is herein incorporated by reference.
Commonly-assigned U.S. patent application Ser. No. 08/977,382, filed Nov. 24, 1997, entitled “Electronic Camera With Utilization Selection Capability” and U.S. patent application Ser. No. 09/004,046, filed Jan. 7, 1998, entitled “Network Configuration File for Automatically Transmitting Images from an Electronic Still Camera” to Ward et al., the disclosures of which are herein incorporated by reference, disclose digital cameras which are provided with host software that enables templates, e-mail addresses, and other information to be selected at the host computer, downloaded to the digital camera, and used, for example, to automatically produce prints and e-mail images. Although this enables user-selected information (such as preferred templates and personalized e-mail addresses) to be downloaded to the digital camera, the actual features of the digital camera normally remain the same for all users who have the same camera model.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the present invention to customize a camera based on demographic factors.
It is a further object of the present invention to enable the customer or retailer to customize a digital camera based on demographic factors.
It is yet another object of the present invention to enable a user to easily add or remove the features that the user wants or does not want, to a digital camera that has been customized based on demographic factors.
These objects are achieved by a method for customizing a camera for at least one particular demographic group by storing at least one parameter value in a programmable memory of the camera to control at least one operation of the camera, the method comprising the steps of:
-
- a) identifying at least one camera parameter having a preferred value for at least one demographic group that differs from the standard value for said parameter;
- b) selecting a demographic classification for the camera; and
- c) programming the programmable memory of the camera to set the parameter value to the preferred value for the selected demographic classification.
It is an advantage of the present invention to enable film and digital cameras to be customized for different demographic groups.
It is another advantage of the present invention to enable efficient, inexpensive customization of cameras in cases where different characteristics are required to optimize image quality and minimize cost for different demographic groups.
The inventors of the present invention have conducted experiments which determined that the severity of redeye is a strong function of demographic classification of the subject photographed. This is due to two effects. First, more highly pigmented races tend to have more melanin in their pupils, which attenuates the light propagating through the pupil via absorption, and reduces the amount of red light exiting the eye. Second, as people age, the maximum diameter to which their pupil will dilate at low light levels decreases. Consequently, young people exhibit larger pupil sizes than older people under the conditions in which flash photographs are typically taken. The dramatic nature of the dependence of redeye severity on demographics is demonstrated in Table I, which shows the frequency of occurrence of noticeable redeye in over one hundred subjects belonging to different demographic groups and photographed under rigidly controlled conditions (0.1 foot-candles ambient light; 2.6 inch flash to lens separation; subject distance 6 feet; no preflash; focal length 80 mm; normally viewed 4×6 inch print from 35-mm format film).
Both the pigmentation and age affects are evident in this data, although the age effect is more obvious at 3.8 inches flash to lens separation (with other parameters the same), where Caucasian adults exhibit redeye only 20% of the time, but Caucasian youth show redeye in 67% of photographs.
These data demonstrate that, whereas a camera targeted at the youth market in the United States might require preflash, greater flash-lens separation, and optical and/or electronic zoom restrictions to control redeye successfully, a camera intended for an Asian market might require none of these features, with potentially significant improvements in size, cost, and image quality.
In an embodiment of this invention, the demographic data is used to customize the fashion in which the camera sets the zoom factor, the preflash output, and/or the flash-lens separation distance. For example, Table II shows combinations of zoom factor, preflash output, and flash-lens separation distance, which yield the same average image quality loss due to redeye for four different demographic groups. The older and/or more pigmented groups require less restriction of zoom factor, less preflash output (a guide number of zero corresponds to an absence of a preflash entirely), and less flash-lens separation due to their lower propensity to redeye. These results are for a camera to subject distance of 10 feet, an ambient light level of 3 foot-candles, a zoom factor one corresponding approximately to normal perspective, and an average quality loss of 1.5 just noticeable differences.
A second example of camera properties for which different demographic groups might have different preferences is in the area of color and tone reproduction, particularly with regard to skin-tone rendition. Experiments have shown that the preferred rendering of skin tones is not a perfect match to the actual skin tone color; for example, some fair-skinned races like to appear more tanned in a photograph than they actually are. Experiments have shown that the shift between true color and preferred color for skin tones are different for different demographic groups. Consequently, a single color reproduction position is not optimal for all demographic groups. Table III demonstrates the magnitude of this difference in preference. The percentages of Caucasians and Chinese who prefer the average Caucasian optimum position and the average Chinese optimum position, which is relatively lighter and warmer in color balance, are compared.
These data demonstrate that it is very advantageous to optimize the color and tone reproduction of a camera to account for demographic preference.
Table IV shows how color and tone reproduction parameters might be changed to customize a camera with optimal reproduction for Caucasians to produce optimal reproduction for a Chinese market. A tone correction lookup table is generated by a tone correction function that relates the uncorrected code value x to the corrected code value y. The values a, b, and c are constants chosen to optimize the reproduction under certain circumstances, in this case for the Caucasian demographic group. The change in the tone correction function for Chinese customization lightens the image. Similarly, the color correction matrix shown, which is representative of current digital still cameras, is assumed to be optimized for Caucasian preference. The change in the color correction matrix for Chinese customization shifts the color balance in a warmer direction. Four of the nine matrix elements are altered.
Other examples of demographically based customization may be envisioned based on regional usage profiles. For example, in some countries, such as India, relatively more images contain people as their primary subject, and relatively fewer pictures are of scenery or buildings, as are often photographed on vacations. In such circumstances, image processing pathways could be customized for rendition of people rather than scenery and buildings, for example by decreasing sharpening, increasing noise reduction, decreasing color saturation, etc. In addition, different color can have different connotations in different countries. Therefore, the preferences for the background color used in a graphical user interface on a digital camera can be demographically based.
In accordance with one preferred embodiment of the present invention, the firmware stored in the Flash EPROM 28 of the digital camera is customized by the vendor based on demographic factors by the vendor computer 740, and provided to the purchaser along with a CD-ROM disc 32, floppy disc 34, or other digital storage media containing camera customization software. This camera customization software is then executed external to the digital camera 10, typically on the purchaser's host computer 40. The software code can include source code, which is compiled by the camera customization software to create executable firmware. Alternatively, the software code can include compiled firmware components or firmware settings which are accessed by the camera customization software. The camera customization software can modify or combine firmware components in order to provide firmware which customizes the digital camera 10 for a particular user. The camera customization software can also include one or more applications that provide a series of interactive dialogues with the user so that the user may learn about available camera features and select features of interest. In an alternative embodiment, the vendor computer 740 is not used, and the digital camera 10 is provided using the same firmware independent of demographic factors. The camera customization software executed on the purchaser's host computer 40 instead accesses software code which permits the firmware in the digital camera 10 to be customized based on demographic factors.
In another alternative embodiment, the purchaser's host computer 40 is not used, and the vendor (e.g. a retailer) customizes the digital camera 10 using the vendor computer 740 based on demographic factors. In this embodiment, the vendor can also customize the digital camera 10 in accordance with purchaser decisions made at the time of sale.
As shown in
The image sensor 14 can be, for example, a single-chip color charge-coupled device (CCD) or CMOS image sensor, using the well-known Bayer color filter pattern. When the user depresses a shutter button 15 (shown in
The processed digital image file is provided to a memory card interface 20 which stores the digital image file on the removable memory card 30 or on another type of digital memory device, such as a floppy disk or magnetic hard drive. The removable memory card 30, which is well-known to those skilled in the art, can include, for example, a memory card adapted to the PCMCIA card interface standard, as described in the PC Card Standard, Release 2.0, published by the Personal Computer Memory Card international Association, Sunnyvale, Calif., September 1991. The removable memory card 30 can also be adapted to the Compact Flash interface standard, such as described in the CompactFlash Specification Version 1.3, published by the CompactFlash Association, Palo Alto, Calif., Aug. 5, 1998, or to other memory devices such as the well-known SSFDC (Solid State Floppy Disc Card) or Memory Stick formats.
The processor 18 performs color interpolation followed by color and tone correction, in order to produce rendered sRGB image data. This processing is described later with reference to
After a series of images has been taken by the digital camera 10 and stored on the removable memory card 30, the removable memory card 30 can be inserted into a memory card reader 48 in the host computer 40. Alternatively, an interface cable 36 can be used to connect between a host interface 26 in the digital camera 10 and a camera interface 46 in the host computer 40. The interface cable 36 may conform to, for example, the well-know universal serial bus (USB) interface specification.
The captured images from the digital camera 10 can be downloaded to the purchaser's host computer 40 and stored on a hard drive 56 under the control of a central processing unit (CPU) 50. The CPU 50 is coupled to a display monitor 52, which is used to view the images, and a keyboard 54. A mouse 55 permits the user to readily communicate with the CPU 50. The CPU 50 communicates with a 25 local printer 58, such as an Epson Stylus Photo 700 printer, which produces hard copy prints of the images captured by the digital camera 10.
The digital camera 10 that is supplied to the purchaser includes firmware stored in the Flash EPROM 28, which is programmed into Flash EPROM 28 using the vendor computer 740 before the camera is purchased, and provides normal camera features for the demographic group selected by the camera vendor. The vendor computer 740 operates under the control of a central processing unit (CPU) 750, and includes a hard drive 756. The hard drive 756 stores a plurality of camera firmware files (e.g. software programs that are used to control the operation of the processor 18 in the digital camera 10) to enable the camera 10 to be customized based on demographic factors, such as the location (e.g. country) where the camera 10 will be sold, and/or the likely age of the camera user. The CPU 750 is coupled to a display monitor 752 and a keyboard 754. A mouse 755 permits a representative of the vendor to readily communicate with the CPU 750 in order to make demographic selections from a menu of options. The CPU 750 communicates with a label printer 758, 7 which produces a label identifying the selected demographic group, which can be affixed to a box or other packaging into which the digital camera 10 is placed.
Users can further customize the look and feel, and the functions offered by the digital camera 10, using the camera customization software provided with the digital camera 10. This camera customization software is provided on the CD-ROM disc 32, which is loaded into the host computer 40 via the CD-ROM drive 42, or provided on the floppy disk 34, which is loaded into the host computer 40 via the floppy disk drive 44. The CD-ROM disc 32 or the floppy disk 34 can also include digital image application software, such as the Picture Easy™ version 3.1 software developed by the Eastman Kodak Company. Alternatively, this camera customization software can be downloaded from the Network Service Provider 70 via a modem 60. The modem 60 communicates with a modem 72 at the Network Service Provider 70, which is connected to a computer 74, a camera firmware database 76, and a billing system 78 which can charge the user (e.g., via a credit card) for downloading the camera customization software.
The CPU 750 and the CPU 50 transfer firmware to the Flash EPROM 28 in the camera 10 via the removable memory card 30, as described in commonly-assigned U.S. Pat. No. 5,477,264, entitled “Electronic Imaging System Using a Removable Software-Enhanced Storage Device” to Sarbadhikari et al., or via the interface cable 36 as described in commonly-assigned U.S. Pat. No. 5,734,425, entitled “Electronic Still Camera With Replaceable Digital Processing Program” to Takizawa et al., the disclosures of which are herein incorporated by reference. The process of storing firmware code in an EPROM and of erasing firmware code from an EPROM is well known in the art, and need not be discussed in detail.
In one embodiment of this invention, the demographic data is used to customize the fashion in which the processor 18 in the digital camera 10 sets the output of the preflash (e.g. the redeye reduction flash) provided by the flash unit 21, and sets the tone correction lookup table 532, and the color correction matrix 522, as was described earlier in relation to Table III and Table IV, and sets the background color, language, and icons used for the camera user interface.
In block 104, a demographic classification for a camera is selected. The selection can be made using the mouse 755 or keyboard 754 in conjunction with the display monitor 752. The demographic classification can be made by ascertaining the expected demographic classification distribution of purchasers based on regional destinations of the product. For example, a large group of cameras being manufactured may be destined for sale in Asia, and therefore an “Asian heritage” demographic classification is selected for each camera in this group. Alternatively, a group of cameras may be distributed using a particular type of retail store that caters to a particular age group (e.g. youth, senior citizens, etc.). In this case, an appropriate age demographic classification may be selected instead of (or in addition to) a heritage classification. Alternatively, a single camera may be manufacturer in response to a particular customer order, for example an order taken over the Internet, as described in commonly-assigned U.S. patent application Ser. No. 09/534,469, entitled “Configuring and purchasing imaging devices,” to Parulski, the disclosure of which is herein incorporated by reference. In this case, the purchaser can provide both age and heritage demographic information.
In block 112, the firmware providing the preferred parameter values for the demographic classification selected in block 104 is programmed into the digital camera 10. This can be done by transferring firmware containing the preferred parameters from the hard drive 756 to the digital camera 10 via the interface cable 36 using the interface 746 or via the memory card 30 using the memory card reader 748. The hard drive 756 can store customized versions of the firmware, each particular version providing preferred parameter values for one demographic classification. The firmware includes a code identifying the corresponding demographic classification. The label printer 758 is used to produce a label (not shown), which identifies the demographic classification, and the label is attached to a box (not shown) which is used to contain the digital camera 10.
In block 114, a user purchases the digital camera 10.
In block 125, the user connects the digital camera 10 to their host computer 40 via the interface cable.
In block 130, the camera customization software then determines the capabilities of the digital camera 10 and demographic classification of the firmware currently stored in the Flash EPROM memory 28 of the digital camera 10. The capabilities of the digital camera 10 can be determined either by determining the camera model number or by determining the types of hardware features that the digital camera 10 can support and by the size of the memory of the Flash EPROM 28.
In block 140, the camera customization software determines which feature firmware components are available for this particular model camera via the software provided on the CD-ROM disc 32. In block 150, the camera customization software uses the modem 60 to determine whether the firmware components which provide the new features not stored on the CD-ROM disc 32 are available within the camera firmware database 76 at the Network Service Provider 70. The response from the Network Service Provider 70, received by the host computer 40, might include some firmware components that are available to the user at no charge, and other firmware components for which the user will be charged. In addition, the Network Service Provider 70 can track whether the user has previously purchased firmware components so that they can be downloaded again at no charge if the firmware component was lost by the user, or is otherwise unavailable. Further, the Network Service Provider 70 could offer discounts to the user based on previous purchases.
In block 160, the features provided by the available firmware components are displayed to the user on the display monitor 52 through an on-screen listing of these features. An example screen 53 listing available features is shown in
The features displayed in the example screen 53, and the order in which features are displayed, can be based on the demographic classification of the user, as provided by the code identifying the demographic classification stored as part of the firmware in Flash EPROM 28. Certain types of themes (e.g. Halloween special effects) are of much greater interest to some demographic classifications than to others.
To consider a particular option, the user clicks on a particular option line in the product option window 310, for example, the “Beastly Vampires” line 318, which highlights this line in the product option window 310, for example, by making the text bolder than the other lines, or changing the color of this line. A description window 340 provides a brief description of the option. In this example, the option is a package of features designed for the Halloween season that includes the ability to add custom borders and special digital picture overlays with a Halloween theme. It includes two different vampire border templates, and the ability to selectively paint “blood” on pictures of faces captured by the digital camera 10. If this component is selected by the user in block 180, the appropriate firmware will be added to the Flash EPROM memory 28 of the digital camera 10 in block 210 to control the processor 18 to enable the user, via the camera user interface 24, to selectively add the vampire border templates to specific images and to paint “blood drops” in appropriate areas of the images they have captured using the digital camera 10, as the image is displayed on the color image display 22.
The product option window 310 can display many different types of optional features and functions, which will be described later. Some of these are listed in the product option window 310 shown in
The options also include an “album” option that enables the user to upload, from the host computer 40 to the digital camera 10, particularly memorable personal images from various sources that are stored in the Flash EPROM memory 28, and for display on the color image display 22 or the TV display 31. These “album” images are compressed and stored as appropriate resolution images, typically having a greatly reduced number of pixels (and therefore a much smaller file size) than the images captured by the digital camera 10 and stored in the removable memory 30.
The options further include a web-page generator that automatically generates an html file using the captured images, as well as one or more of the stored album images. This feature may be customized by the user as part of the process depicted in
In block 170 of
In block 180, the user selects the feature(s) that the user wants to be included in his/her digital camera 10. This is done by highlighting the desired options in the product option window 310 and then chooses a “select” selector 342. The user can start with a previous camera selection by selecting a “restore” selector 332, which permits the user to select and restore a camera feature set that was previously backed up, and use that as the starting point for a new feature set.
When one or more features must be purchased from the Network Service Provider 70, the purchaser selects a “purchase” selector 324 which provides a series of order menus (e.g., HTML web pages) generated by the Network Service Provider 70 and communicated to the computer 40 via the modem 60. The user pays for the firmware component(s) corresponding to the selected feature(s) by providing a payment identifier into a secured electronic commerce link which specifies a particular account which is to be charged or debited. The payment identifier can be a credit card number that specifies a particular credit card account. As used in this specification, a credit card will also include a debit card. The number of features that can be selected depends on the size of the firmware component(s) needed to implement the features, and the size of the firmware memory in the camera's Flash EPROM 28.
In block 190, the user is provided with the ability to modify the icon schemes and background colors for then demographically selected camera Graphical User Interface (GUI) 25 provided by the firmware stored in the Flash EPROM 28 of the digital camera 10 in block 112. The GUI 25 is displayed on the color image display 22 of the digital camera 10, shown in
Two different exemplary types of demographically based icons schemes are shown in
A representation of a film strip 260 at the bottom of the GUI screens including three small images (i.e., thumbnails), and a memory bar 262 is shown in
In block 200 of
Note that by selecting the “view” selector 320 shown in
In block 106 of
In block 114, the user purchases the digital camera 10. The same digital camera 10 is purchased by all users, regardless of demographics.
In block 125, the user connects the digital camera 10 to the host computer 40, as was described earlier in relation to
In block 135 of
In block 145, the user selected radio buttons in
In block 155, the parameter value selections are communicated to the digital camera 10 over the cable interface 36.
In block 165, the parameter value selections are stored in the Flash EPROM memory 28 of the digital camera 10.
Therefore, the process depicted in the flow chart of
In addition to customizing the digital camera 10 based on demographic factors, the camera customization software executed by the CPU 50 can provide the user with the ability to select from many different features that may be provided by the firmware executed by the processor 18 in the digital camera 10.

The camera firmware stored in the Flash EPROM 28 is customized at the time of purchase, for example by a clerk operating a computer and selecting an appropriate demographic group for the user, or by a customer-operated kiosk.
In another embodiment, the camera customization software permits two or more different users to customize the digital camera 10 based on demographic input, and to store the corresponding firmware components or firmware settings in the Flash EPROM 28. When the digital camera 10 is powered on, a list of users is displayed on the color image display 22 and the user selects their name using the camera user interface 24. In response to this user input, the processor 18 uses the appropriate firmware components or firmware settings stored in the Flash EPROM 28 to provide the demographically customized camera GUI and feature set for that particular user. Alternatively, when the digital camera 10 is powered on, the settings for the last user can be employed, and a camera preferences menu can be used to select a different user.
The Bayer pattern color filter array data (block 500) which has been digitally converted by the A/D converter 16 is interpolated in block 510 to provide red, green and blue (RGB) image data values at each pixel location. The color filter array interpolation in block 510 can use the luminance CFA interpolation method described in commonly-assigned U.S. Pat. No. 5,652,621, entitled “Adaptive color plane interpolation in single sensor color electronic camera” to Adams et. al., the disclosure of which is herein incorporated by reference. The color filter array interpolation in block 510 can also use the chrominance CFA interpolation method described in commonly-assigned U.S. Pat. No. 4,642,678, entitled “Signal processing method and apparatus for producing interpolated chrominance values in a sampled color image signal”, to Cok, the disclosure of which is herein incorporated by reference.
To provide multiple resolution images, for example, a full resolution image and a reduced resolution image, the color filter array 20 interpolation in block 510 can use the method described in commonly-assigned U.S. Pat. No. 5,493,335, entitled “Single sensor color camera with user selectable image record size”, to Parulski et. al., the disclosure of which is herein incorporated by reference.
The RGB image data is color corrected in block 520 using, for example, the 3×3 linear space color correction matrix 20 depicted in
The color corrected image data is tone corrected in block 530. This tone correction 530 can use, for example, the lookup table corresponding to
The image sharpening provided in block 540 of
The image compression provided in block 550 of

5. The method of claim 4 wherein the parameter value provides a plurality of matrix coefficients which control the color correction provided by the digital camera.
6. The method of claim 1 wherein the demographic classification is selected by a camera user.
7. The method of claim 6 wherein the demographic classification is selected using a software program which displays a plurality of demographic classifications to the user.
8. The method of claim 1 wherein the demographic classification is selected as the camera is manufactured.
9. The method of claim 1 wherein the demographic classification is selected as the camera is sold to a user.
10. A digital camera configured according to the method of claim 1.
11. A computer readable medium having computer executable instructions for performing the method of claim 1.
12. The method according to claim 1 wherein the camera includes first and second camera graphical user interfaces responsive to firmware stored in the programmable memory, wherein the first camera graphical user interface is configured for a first demographic classification, and the second camera graphical user interface, which is different from the first camera graphical user interface, is configured for a second demographic classification.
13. The method according to claim 12, wherein the first and second camera graphical user interfaces use different icon styles.
14. The method according to claim 12, wherein the first and second camera graphical user interfaces use different color sets.
15. A method for customizing cameras for a first demographic group and at least one other demographic group as the cameras are manufactured, the method comprising the steps of:
- a) identifying a particular camera feature which is more important for the first demographic group than for the second demographic group;
- b) classifying the cameras based on the expected heritage of one of the demographic groups; and
- c) customizing the cameras classified using the first demographic group such that only these cameras are manufactured in a way that includes the particular camera feature wherein the particular camera feature reduces redeye.
16. The method of claim 15 wherein the particular camera feature provides an increased flash to lens distance.
17. The method of claim 15 wherein the particular camera feature provides a pivoting flash.
